Sonos Sounder

Electronic sounder certified to EN54.

With the TimeSaver base, connections are made to the base during the initial wiring phase which results in faster and more reliable installation. The sounder head ‘twists and clicks’ into the base on commissioning, avoiding the wiring and connection problems associated with traditional sounders.

With a choice of 32 tones including all the major international standards, the Sonos Sounder has universal acceptance.

Deep base units have weatherproof protection to IP65 and can be used in all locations both indoors and outdoors.

Sonos Sounder units are available in either red or white and with a choice of deep or shallow TimeSaver base.
